Gatsby Icarus Theme Starter is a Gatsby v3 blog starter that recreates the Icarus theme from Hexo, letting you build a static blog like Kun's Blog from markdown content. It is open source, hosted on GitHub under the Kun8018/gatsby-starter-icarus-blog repository, and is designed to deploy to Netlify with one click.
What is Gatsby Icarus Theme Starter?
Gatsby Icarus Theme Starter is a Gatsby v3 starter that builds a static blog website with an Icarus-like theme (from Hexo) and markdown-based content management. It takes markdown files from the src/content directory as input and produces a fully functioning static blog with pagination, tags, and comments, ready to deploy to Netlify or GitHub Pages. The starter is maintained by Kun8018 and is available as an open-source GitHub repository.
Key Features
- Gatsby v3 engine — uses GatsbyJS v3 for faster builds, offline support via service workers, and a Web App Manifest for installability.
- Google Analytics — built-in integration; you add your tracking ID in the configuration file to start collecting site analytics.
- Gitalk comment component — comments are powered by Gitalk, a GitHub issue–based commenting system, configured with client ID, client secret, repository, and owner details.
- SEO and sitemap — includes search engine optimization and automatic sitemap generation for better indexing.
- Pagination and tags — posts are organized with page pagination and can be grouped under different tags.
- Responsive design — the layout is fully responsive and styled with SCSS, closely resembling the Icarus theme from Hexo.
- Markdown content authoring — write posts as Markdown in
src/content, or edit them through the built-in Netlify CMS support. - TypeScript support — the starter supports TypeScript for developers who prefer typed JavaScript.
Who is it for?
- Bloggers who want a modern Gatsby-based blog with a clean, card-style layout similar to Hexo's Icarus theme.
- Developers who want a ready-made starter with SEO, offline support, and comment integration so they can focus on writing content.
- Netlify users who want one-click deployment through the Netlify Deploy button, which automatically creates a GitHub repository and publishes the site.
- Hexo users looking to migrate to Gatsby while keeping an Icarus-like look and feel.
Use cases
- Personal blog: publish technical or personal articles as Markdown files and get a static site with tags, pagination, and analytics.
- Documentation or notes site: use the markdown pipeline and sitemap to create a lightweight documentation hub.
- Comment-enabled writing: enable Gitalk comments so readers can discuss posts via GitHub issues without building a custom backend.
How does it work?
- Click the "Deploy to Netlify" button, authenticate with GitHub, and choose a repository name — Netlify creates a copy of the starter, builds it, and deploys the site.
